It took about 25 firefighters to put out the fire. Traffic along Route 3 was slowed to a crawl while crews battled flames. Electrical wires fell into the flames, making a popping noise.

A woman and two children inside the home made it out safely, officials said.

“Very, very, very bad fire,” said Chief Ray Fischer of the Boscawen Fire Department. “The garage was fully involved even before we even came here, and of course, that’s attached to a Cape-style house.”

Fire officials are investigating the cause of the fire, which caused heavy damage.
